#-----------------------三、面板区-----------------------------------------    

#---------------一、窗口---------------------
root=tk.Tk()        
root.title('音乐播放器')
root['bg'] = 'DimGray' 
root.geometry('480x400')
root.resizable(0,0)


#---------------二、显示正在播放的歌曲--------------------------

entry_var = tk.StringVar()
entry_var.set(SongName[Number])
en1=tk.Entry(root,textvariable=entry_var,justify=CENTER,state=NORMAL)                       
en1.place(x=50,y=70,width=210,height=15) 

entry_var1 = tk.StringVar()
entry_var1.set('00:00')
en2=tk.Entry(root,textvariable=entry_var1,justify=CENTER)                       
en2.place(x=5,y=30,width=70,height=15) 


#---------------三、音量调节----------------------------

b3=tk.Button(root,text="+",command=fun4)
b3.place(x=50,y=90)

b3=tk.Button(root,text="-",command=fun5)
b3.place(x=65,y=90)



#---------------四、切换歌曲|暂停播放----------------------------------
#1.上一曲按钮
b1=tk.Button(root,text="上一曲",command=fun1)
b1.place(x=80,y=90)


#2.播放按钮
condition = tk.StringVar()
condition.set("暂停")

b1=tk.Button(root,textvariable=condition,command=fun2)  #定义：按钮名称+按钮功能
b1.place(x=130,y=90)          #定义：按钮大小+按钮位置


#3.下一曲按钮
b3=tk.Button(root,text="下一曲",command=fun3)
b3.place(x=167,y=90)


#4.播放模式
model = tk.StringVar()
model.set("顺序")
model_value=0
b4=tk.Button(root,textvariable=model,command=play_model_set)
b4.place(x=225,y=90)



#--------------五、下载功能------------------------------


#1.搜索
en3=tk.Entry(root,justify=CENTER,state=NORMAL)                       
en3.place(x=50,y=150,width=80,height=30) 

b1=tk.Button(root,text="搜索",command=Search)
b1.place(x=135,y=150)

#---------------------------------------------------------

#2.下载
en4=tk.Entry(root,justify=CENTER,state=NORMAL)                       
en4.place(x=180,y=150,width=35,height=30) 

b1=tk.Button(root,text="下载",command=DownLoad_music)
b1.place(x=225,y=150)


#3显示下载内容
txtCon=tk.scrolledtext.ScrolledText(root,wrap=tk.WORD)
#txtCon.pack(fill=tk.BOTH)
txtCon.place(x=50,y=200,width=210,height=180)


#------------------------------六、定义滑动条-------------------------

def slide(text):
    global set_time
    global Outer_executeCount
    audio = MP3(SongPath[Number])    
    Song_length=audio.info.length//1
        
    Get_Length=int(float(value.get()))
    rate=Get_Length/100;
     
    set_time=Song_length*rate
    pygame.mixer.music.rewind()
    pygame.mixer.music.set_pos(set_time)
    
    Outer_executeCount+=1

    print("当前时间",pygame.mixer.music.get_pos()//1000)

  

value = StringVar()
value.set("0")
Scale(root,from_=0,to=100,orient=HORIZONTAL,length=480,show=0,variable=value,resolution=0.01,command=slide).pack()

#-----------------------------------七、定义音乐列表----------------------------------------------

def Select(event):
    global Number
    songname=listbox1.get(listbox1.curselection())   
    Number=int(songname.split(".")[0])-1
    print(Number)
    pygame.mixer.music.load(SongPath[Number])  
    pygame.mixer.music.play(0)
    entry_var.set(SongName[Number])

def  listbox_Show():
    num=1    
    for i in SongName:
        Num=str(num)+"."
        listbox1.insert(END,Num+i)
        num+=1 
        
        
#1.界面-------------------------
scrollbar1 = Scrollbar(root)
scrollbar1.pack(side=RIGHT, fill=Y)
 
listbox1 = Listbox(root,height=20,width=22)
listbox1["yscrollcommand"] = scrollbar1.set

listbox1.pack(side=RIGHT)
scrollbar1["command"] = listbox1.yview

listbox1.bind('',Select)







#------------------------------------------------------------------

#1.初始播放------------------------------
def init_play():
    pygame.mixer.init()
    pygame.mixer.music.load(SongPath[Number])  
    pygame.mixer.music.play(0)
    play_model()
    listbox_Show()

init_play()
#--------------线程区--------------------------

#2.播放进度条
t1=Music_PlaySlide()
t1.start()

#3.界面主线程
root.mainloop()
#---------------------------------------
pygame.mixer.music.stop()
